SPECIFICATION formingpart of Letters Patent No. 730,004, dated June 2,1903. Application filed July 22, 1902. Serial No. 116,486. (No model.)

To rtZZ whom it may concern.

Be it known that I, J OSEPH HENRY GorrER, a subject of the King of GreatBritain, and a resident of Winnipeg, in the Province of- Manitobaand'Dominion of'Oanada, have invented a new and Improved Domestic Refuse- .Grematory, of which the following is a full,

vide means adapted to expose a large area of the refuse to the action ofan incandescent 'bed of fuel, to allow the refuse to be partiallyembedded in the fuel-bed incontradistinction to a mere suspensionthereover in order to secure better and quicker results, to provide forthe free ingress of air to the burning part of the refuse so as toproperly support combustion, and to provide means by which a limitedvertical play is permitted to the refuse-container in order that it maysink into the bed of fuel as the latter is consumed.

To the accomplishment of these ends my invention consists of a domesticcrematory embodying certain novel featu res of construction andarrangement, which will be hereinafter fully described and claimed.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar characters of reference indicatecorresponding parts in both thefigures.

Figure 1 is a vertical sectional elevation through a refuse-crematoryapplied in operative position to an ordinary cooking-stove, and Fig. 2is a detached perspective view of the refuse-container.

5 designates an exterior shell or jacket, which is provided with aremovable cover 6 at its upper end, said cover being equipped with asuitable handle 7, and the jacket is, furthermore, provided with handles8, which are secured to the opposite sidesthereof. The jacket or shellis open at its lower end, and it is adapted to be placed on the top of acooking-stove in a position to inclose one of the lid-holes therein.Within the jacket is arranged arefuse-container 9, which is shown by thedrawin s in theform of a wire basket,

the'same fitting loosely within said jacket and preferably. suspendedtherein by means which permit said container to have a limitedindepend'entmovement or play. Although I have shown this container asconstructed of heavy wire fabric, it will be understood that anyappropriate material may be employed in the manufacture of thebasket-as, for example, sheet metal or other foraminous metallicsubstance. 1 The basket or container is open at its upper end in orderthat refuse may be easilyintroduced therein when the cover 6 is removedfrom the exterior shell or jacket, and

this basket is preferably cylindrical in form,

although the shape is not material.

The bottom 10 of the basket or container is inclined, as shown moreclearly by Fig. 1,. and one side of the basket is considerably shorterthan the other side, thus-allowing the long side of the basket to extendwell down and into the combustion-chamber or fire-box 11 of an ordinarycooking-stove, which is indicated partly at 12. The basket, having theinclined or sloping bottom, may be loosely suspended within the jacketor shell by any preferred means; but, as shown by the drawings, thesuspending means comprise a series of chainsor their equivalents 13, thelatter being fastened to the edge of the open-mouth ,portion of thecontainer and tosuitablc hooks or eyes 14., which are firmly attached tothe inside of. the jacket or shell at a suitable distance below theremovable cover 6 thereof.

15 dcsignates an air inlet or supply tube which is arranged to extendinto the basket "or container and is adapted to have communication withthe outer surrounding atmos- 'phere,and in the service of the crematorythis tube supplies the air to the lower burning part of the refuse inorder to properly support combustion. If, desired, the air-inlet tubemay be attached to the jacket or shell 5 and arranged to fit loosely ina suitable opening provided in the basket or container; but in view ofthe fact that the basket is adapted to have a limited vertical playwithin the jacket I have shown the air-inlet tube as being attached tosaid basket or con tainer in order-that it may travel or play therewith.The upper end of the inlet tube is disposed adjacent to or arranged toplay in an air-feed opening 16, which is provided in one side of thejacket or shell 5, at the lower part thereof. Any suitable means may beadopted for attaching the inlet-tube securely to the basket in orderthat it may travel therewith, and this tube is adapted at all times tohave communication with the surrounding atmosphere through the inletopening or port 16.

In using my improved device the garbage and other refuse may beintroduced into the container or basket before the structure is placedon the cooking-stove, or said structure may be first placed in positionand then the v refuse may be introduced into the container, the cover (3being removed for this purpose. The shell is adapted to rest snugly uponthe top of the cooking-stove, and the cover 6 serves to close theshell,'except at the airinlot 16, thus preventing the escape into theroom of any fumes or odors which may arise from the refuse during theoperation of oremating the same.

The inclined or sloping bottom of the container is of considerableimportance, because it provides a larger area of the mass of refuse,which is exposed to the action of the heat, and the bottom furthermoremakes the lower part of the basket or container extend Well into thefire-box or combustion-chamber of the stove. In fact, the lower part ofthe container or basket is adapted to be embedded into the mass ofincandescent fuel on the grate, thereby securing a better and quickerefifect in the reduction of the garbage. At the same time the heat andproducts of combustion are free to circulate through the basket and intothe flue of the stove, and the tube 15 supplies the necessary air intothe body of the burning refuse, thus promoting the combustion.

As the bed of incandescent fuel sinks or decreases in volume, the basketis adapted to automatically lower itself in order to properly presentthe refuse to the action of the heat, and this is secured by theemployment of flexible suspension-chains which serve to limit thedownward movement or displacement of the basket that is suspended fromthe stationary jacket or shell.

Having thus described my invention, I claim as new and desire to secureby Letters Patentl. A domestic .refusecrematory having a shell orjacket, a container housed therein, and means for loosely suspendingsaid container and permitting it to be lowered by gravity relative tothe shell or jacket within the limit of the suspension means.

2. A domestic refuse-crematory, co1nprising a suitable shell or jackethaving an airinlet, a container within said shell or jacket, and aninclined air-tube extending into the container toward the bottom thereofand having communication with the air-inlet of the shell or jacket.

3. A domestic refuse-crematory, consisting of an exterior shell orjacket having an airinlet, a container provided with an inclined orsloping bottom, means for loosely suspending said container within saidshell or jacket and permitting the container to have a down- Wardmovement within the limit of said suspension means, and an air-inlettube extending into said container and movable therewith.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

JOSEPH HENRY COTTER.
